Maple syrup

Listed nutrients, per 100 g

For each nutrient, the value this page uses is marked “used”. A row marked “second database” is another database’s figure for a matching food, kept so you can see how far databases disagree (they can differ in the samples analysed, lab methods and rounding). Its own cells are worked out from it, but none of the page’s words or scores are.

Change the amount to rescale the first column. Nutrients a database doesn't list are missing, not zero.

Hazard rows as the dataset rates them

• Formaldehyde · Context · Context only (never scored: no health-based limit was opened). A pesticide-residue positive here is not the same as use: untreated Quebec maple syrup carries formaldehyde of its own, averages 0.18 mg/kg (2000) and 0.28 mg/kg (2001) in 300 authentic samples with maxima of 1.04 and 1.54 mg/kg (Lagacé 2003), against CFIA's positives-only mean of 0.399 µg/g (equal to mg/kg) and maximum 1.32. The CFIA positives sit inside the natural range, and heat treatment of syrup raises formaldehyde further. · CFIA chemical residue monitoring (2016–2023) · A
• Lead · Nothing to watch: doesn’t double average intake · No cap: no safe threshold is set for lead; EFSA's 2010 reference point is a benchmark dose lower limit (BMDL01) of 0.5 µg/kg body weight/day. Judged by what a daily 79.9 g serving adds to the average adult's intake (35 µg a day): 0.91 µg (2.6%) at the 2016–2023 pooled lower-bound mean, and 0.27 µg (0.8%) at the 2020–2023 lower-bound mean of 0.00336 µg/g. Far from doubling it. The 2016–17 maximum, 0.695 µg/g, is above Health Canada's 0.5 ppm level (the level at which Health Canada says avoidable contamination has occurred); 2 of 567 CFIA tests exceeded it, none after 2016–17 in the annexes read. Background intake is not subtracted. · CFIA chemical residue monitoring (2016–2023) · A

Oxalate, phytate and gut-tolerance measurements

• fodmap excess fructose: none: fructose 0.52 g/100 g is less than glucose 1.60 g/100 g in the listing (fructose minus glucose = -1.08), so excess fructose is 0; per 79.9 g serving 0 g against the 0.40 g cut-off g/100 g · fresh weight, as sold · database listing (USDA SR Legacy 169661, 'Syrups, maple'); not a measurement in a paper · grade B · US food database (USDA SR Legacy)

Body map 2026-10-25.1: each nutrient’s job comes from an agency fact sheet, linked beside it under Good for.

The plain words: “a lot” means one serving (100 g when the food has no serving size) gives at least 20% of the daily amount (the reference intake), “some” at least 10%, “a little” at least 2% (the cut-offs are ours, one set for every page: 20% and 10% are borrowed from the US labelling terms “high” and “good source” and applied to Health Canada’s daily amount, whereas Health Canada’s own shopper rule says 15%; provisional: they may change in a later method version). The daily amount is Health Canada’s Dietary Reference Intake for adults 19–30; where men and women need different amounts we use the higher one (protein: 56 g for men, 46 g for women). The percentage printed under each nutrient is the printed amount as a share of that daily amount, rounded to the nearest whole number, and the word is read from that percentage, so the amount, the percentage and the word always agree. Calcium with a measured absorption is scaled by how well it gets in compared with milk.

The scale: “Nothing to watch” means a serving a day stays under the limit at ordinary amounts; “Go easy” means a serving a day can push past the limit for adults who already take in the most, or fewer than 2 servings reach it; “Limit it” means once a week or less. The dataset’s own rating is under “How we got this”. Provisional: the scale may change in a later method version.

Measured absorption under Good for: grade-A studies in adults that tested this preparation of this food, as a share of the listed amount (the share digested, for protein), quoted once each source has passed our evidence check; animal studies and other variants stay in the table above. Provisional: this screen may change in a later method version.
